The site with the manuals is owned by a fellow named Chris Bryant. Chris used to be active on this and other sites. I should point out that his site contains manuals for most refrigerators, water heaters, furnaces and other appliances. He maintains the site offering these manuals free of charge to us users. I have also had a few questions in past years for him. He has been very responsive and helpful, although I have not had contact with him for several years.
